914World.com _ 914World Garage _ Dumb question about wideband O2 sensor
Posted by: bbrock Jun 26 2022, 12:25 PM
Kind of an odd question but I have a wideband O2 sensor installed I've been using to dial in carbs using my laptop with Logger3 installed for the gauge. I'm going to drive the car on a moderately long trip next week and don't want to leave the cable snaked through the engine lid and targa top when I drive.
I think it was McMark who said the sensors don't like to be installed and uninstalled too many times so I'm wondering if there is any harm in leaving the sensor in place but disconnecting from power and tying the cable out of the way in the engine bay, or should I remove the sensor completely. Is there any harm in leaving the sensor installed by not connected?

Bah! Take it out. No big deal.

I would theorize that the sensor needs to be connected for the internal heater to work. And keep contaminants burned off

Confirms my suspicion. It's coming out. Thanks!

Only two choices, take it out or leave it running, you have to have power to the sensor.
McMark is correct, every time you remove a lambda you risk ruining it. For temporary set ups remove the sensor as soon as you're done, if you leave it in too long it will get stuck. Once it's really stuck you will likely pooch the sensor when removing it.
If you're installing or replacing a sensor it's good practice to chase the threads and use the proper socket, both tap, socket and bung plug are available at your FLAPS. Always use anti-seize on the threads, but be careful not to get any of it on the sensor tip.
Heh-heh I said 'bung plug'

Thanks Mark, The sensor is out and my bung is now properly plugged again.

Another question on a Wideband for the group
I picked up a Innovate Wideband Kit plan to mount the gauge in the center console
cable equates to about 10 and half feet will this be enough to make it ?

All depends on how you route it, for me 10 was slightly short, but the next sized cable is obnoxiously long…
